Summary:1. Field of Invention The present invention relates to an apparatus and method for analyzing the read-out signal of an optical storage media and is especially suitable for the HF signal read from the digital video disk (DVD), wherein the HF signal comprises many different signals whose periods are integer times of the system period. The present apparatus can be used to record the maximum or minimum values of specific period of signals for further statistical analyses. Furthermore, the AC and DC components of the HF signal can be processed independently and the results will be combined together for further processes. Therefore, it only takes moderate memory capacity and acquisition time to obtain accurate maximum or minimum values of the specific period of signals.
